Introduction
The Information Communication Technology (ICT) can significantly improve the living conditions of people with
disabilities. New platforms such as smartphones phablets and tablets, combined with attractive and innovative
applications and services open now new horizons.
Several studies are available on the subject and many websites from association, governmental organization, regulation
or standard bodies provides valuable information.
http://www.e-accessibilitytoolkit.org/toolkit/international_cooperation/international_standards_development
The present document intends to gather some concrete requirements and make proposals for communication
tools/devices/Services/interfaces, for vision impaired people (blind, or low vision, or partially sighted people).
• Blindness is defined by the World Health Organization (WHO) as vision in a person's best eye of less than
20/500 or a visual field of less than 10 degrees. (According to numbers from the WHO, 90% of blind people
live in the developing world).
• Low vision generally refers to a severe visual impairment, not necessarily limited to distance vision. Low
vision applies to all individuals with sight who are unable to read the newspaper at a normal viewing distance,
even with the aid of eyeglasses or contact lenses.
• Partially sighted indicates some type of visual problem.
According to WHO, 285 million people are estimated to be visually impaired worldwide: 39 million are blind and 246
have low vision. 65 % of all people who are visually impaired are aged 50 and older, while this age group comprises
about 20 % of the world's population.
With an increasing elderly population in many countries, more people will be at risk of age-related visual impairment.
Vision impaired people face sometimes insurmountable difficulties when they want to access new technologies using a
computer, Internet access, editing and printing a text, reading a document can be extremely complex tasks despite their
simplicity to another user, but ICT may today give people with vision disabilities capabilities to improve their social
and economic integration in their society if some specific requirements are taken into consideration when product and
services are designed.

1 Scope
The present document aims at identifying use cases for vision impaired people for e-access to ICT products and services
but also use cases to allow users to interact with machines or equipment (e.g. users terminal, user interface) via
dedicated devices (M2M communications) in order to define appropriate protocols (NFC or similar).
The intention is not to define technical solutions but to forward the requirements to the appropriate ETSI Technical
bodies.
Equal access to services, to WEB content, to public places is now required by law in many countries. Vision impaired
people often use of specialized devices which can help them in the current life and also provide access to entertainment
(access to Television, book reader, etc.).
Being able to use computers, mobile phones and other tools for, work, leisure and keeping in contact are key tools for
blind and partially sighted people. In the present document, some requirements and/or proposals in possible assistive
technology for the vision impaired people are listed.
The present document is devided in 3 sections:
• Section 1 where accessibility requirements have already been studied and proposed solutions identified.
However, these requirement are often ignored. This is the case for web and content document accessibility.
• Section 2 where accessibility requirements exist are partially considered, however this report bring some new
considerations and propose recommendations. This is the case for terminals smartphone, phablets, and tablets.
• Section 3 where accessibility requirements are not yet really considered, because several type of requirement
may be requested. This is the case for e-purchasing, Kiosks, Television, M2M, etc.
